Wind Power Management System for Security-Constrained Dispatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of intermittent renewable energy sources, particularly wind power, poses challenges for energy management systems as they struggle to maintain reliable and continuous power distribution, requiring enhanced systems to optimize wind power generation while ensuring grid security and economic efficiency.
Innovation Solution
A wind power management system within an energy management system that determines sensitivity values for wind farms, maximizes wind power generation within security limits, minimizes losses, and optimizes production costs by prioritizing wind farms based on cost and energy bids, using a probabilistic approach to balance security and economics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wind power generation is maximized without restrictions, then renewable energy utilization is improved, but system security and reliability deteriorate due to intermittency
Solution Approach 1:
The system dynamically adjusts wind farm dispatch based on real-time sensitivity values and system conditions. The WPM system continuously recalculates sensitivity values and modifies dispatch decisions to adapt to changing grid conditions, allowing maximum wind utilization when secure and reduced utilization when security concerns arise.
Solution Approach 2:
The system changes operational parameters by determining sensitivity values for each wind farm and using these to define security limits. The WPM system modifies dispatch parameters dynamically based on calculated sensitivity metrics, transforming fixed dispatch approaches into flexible, condition-based dispatch that resolves the contradiction between maximizing generation and maintaining security.
2Reliability
If sensitivity-based security limits are imposed on wind farms, then system security is improved, but wind power generation is reduced due to restrictive limits
Solution Approach 1:
The system applies different security limits to different wind farms based on their individual sensitivity values rather than imposing uniform restrictions. The WPM system calculates unique sensitivity metrics for each wind farm and applies tailored dispatch limits, allowing less sensitive farms to generate more power while restricting only those that pose security risks.
Solution Approach 2:
The system performs preliminary calculation of sensitivity values and security limits before actual dispatch decisions are made. The WPM system pre-determines the sensitivity metrics and establishes security boundaries in advance, enabling optimized dispatch that respects security constraints while maximizing allowable wind generation within those constraints.
3Loss of energy
If wind farms are prioritized by cost and energy bids, then production cost is minimized, but system security may be compromised by favoring cheaper over safer options
Solution Approach 1:
The system segments wind farms into different priority groups based on their sensitivity values and security characteristics. The WPM system creates distinct groups (e.g., high-priority, medium-priority, low-priority) according to sensitivity metrics, then applies cost optimization within each group while ensuring security constraints are met, preventing cheaper but riskier farms from compromising overall system security.
